A few modifications:

1. Finally, clean up some of the crappy code in inc/display.php; no more extreme clutter. new Thread() and new Post() take an array as the first parameter now.

2. Poster country flags. Currently requires the "geoip" extension.

3. Give post images a classname. This was also long-overdue.
